Hope this helps :)
<span>We have to find the product : ( 9 t - 4 ) ( - 9 t - 4 ) = - ( 9 t - 4 ) ( 9 t + 4 ) After that we can use the difference of squares. The formula is: ( a + b ) ( a - b ) = a^2 - b^2. In this case: - ( 9 t - 4 ) ( 9 t + 4 ) = - ( 81 t^2 - 16 ) = - 81 t^2 + 16 . Answer: B ) - 81 t^2 + 16.</span>

a
Step-by-step explanation:
Given:
triangle XYZ is rotated by a composition of 50°+40°=90° both about point y
Now when a geometrical figure is rotated by any degree then its shape or size does not change and remain same.
As the triangle is rotated clockwise by 90 degrees about point y then diagram attached is formed .
option a is correct.
If she studied for 2.3 she would have a total of 11.5 because if she got 5 points per hour you just have to multiply it the number of hours she spent studying. So 2.3 x 5 = 11.5! :-)
